Light emitting diode bulb connector including tension reliever

Abstract

An LED light source ( 10 ) comprises a housing ( 12 ) having a base ( 14 ) with a hollow core ( 16 ) projecting therefrom. The core ( 16 ) is substantially conical. A central heat conductor ( 17 ) is centrally located within the hollow core ( 16 ) and is formed from solid copper. A first printed circuit board ( 18 ) is connected to one end of the central heat conductor and a second printed circuit board ( 20 ) is fitted to a second, opposite end of the central heat conductor ( 17 ). The second printed circuit board ( 20 ) has at least one LED ( 24 ) operatively fixed thereto. A plurality of electrical conductors ( 26 ) has proximal ends ( 28 ) contacting electrical traces formed on the second printed circuit board ( 20 ) and distal ends ( 30 ) contacting electrical traces on the first printed circuit board ( 18 ). Each of the electrical conductors ( 26 ) has a tension reliever ( 27 ) formed therein which axially compresses during assembly. A cap ( 32 ) is fitted over the second printed circuit board ( 20 ); and a heat sink ( 34 ) is attached to the base and in thermal contact with the first printed circuit board.

1. An LED light source comprising:
 a housing having a base; 
 a hollow core projecting from said base, said core being substantially conical; 
 a central heat conductor centrally located within said hollow core; 
 a first printed circuit board connected to one end of said central heat conductor; 
 a second printed circuit board fitted to a second end of said central heat conductor, said second printed circuit board having at least one LED operatively fixed thereto; 
 a plurality of electrical conductors having proximal ends in contact with electrical traces formed on said second printed circuit board and distal ends in electrical contact with traces on said first printed circuit board, each of said electrical conductors having a tension reliever formed therein; 
 a cap fitted over said second printed circuit board; and 
 a heat sink attached to said base and in thermal contact with said first printed circuit board. 
 
   
   
     2. The LED light source of  claim 1  wherein at least two electrical contacts extend from inside said housing to a position outside said housing for connection to a power source. 
   
   
     3. The LED light source of  claim 1  wherein an annular O-ring is positioned between said base and said heat sink. 
   
   
     4. The LED light source of  claim 1  wherein the outside surface of said hollow core has multiple diameters. 
   
   
     5. The LED light source of  claim 4  wherein one of said diameters is provided with a locking flange. 
   
   
     6. The LED light source of  claim 1  wherein said at least one LED comprises at least two LEDs. 
   
   
     7. The LED light source of  claim 6  wherein said at least two LEDs emit light in the same color. 
   
   
     8. The LED light source of  claim 7  wherein said at least two LEDs emit light of different colors.
